SPECIFICATION forming part of Letters Patent No. 396,813, dated January.29, 1889.

Application fi ed January 30, 1888, Serial No. 262,440. (No model.)

To (all 10710721 z'zi Ill fly cancer/1 :Be it known that I, JOHN MASONDUNCAN FRANCE, a citizen of the United States, residing at St. Jos ph,in the county of Buchanan and State of )jiissouri, have invented a newand useful Improvement in a Book-Shelf for Recon'l-l-Eooks, of which the'fo'llowin is a :full, clear, and exact description, reference being hadto the accompanying drawings.

Figure] is a front .view of my im nroved book-shelf. Fig. 2 is a topview of the same, and Fig. 2-) is a perspective view of the same as inoperation.

Myinvent-ion consists in certain features of construction and anovelcombinatirm of parts, as 'will. be hereinafter fully described andclaimed.

In the drawings, A indicates a sliding board or shell, which is providedon opposite sides with metallic bars B The bars B B are provided withmortises M), in which fittenons a a upon the sides of the sliding boardA, as shown. The bars B are also provided with a tongue,b', the purposeof which will be presently explained. In the sides F F of the casing 1are formed horizontal mortises f, into which are fitted the metallicbars C, which bars are provided with the grooves c, extending theirlength. Into these grooves c are fitted to slide the tongues b b of thebars B, which are secured to the sliding board A, as before dercribed.The sliding board A is provided with a suitable handle, G, which servesto facilitate its movement in the easing F.

In the operation of my improvement the sliding board A is drawn out ofthe casing 11, and when a record or other book is placed thereon it maybe readily shoved back into place in the casing. By reason of themetallic bars 1] and U and their tongue-andgroove connections, asdescribcththc casv operation of the device is thereby much tacilitatcd.A l'OCfHtl-IMJUIC being placed on the sliding board and the boardworking in the casing in the manner before specified, said book isbetter preserved and protected from wear and tear incident to otherbook-shelves.

Having thus descri bed my invention, what I claim is In a book-shelf,the combination, with the casin g I and the metallic grooved bars C,socured horizontally in mortises formed in the sides of said casing, ofthe sliding board A, the metallic bars B, secured to the sides of saidboard A, said bars '13 provided with a mortise, b, to receive the tenona of the board A, and a tongue, Z), adapted to fit and slide in thegroove 11 of the bar (J, substantially as and :for the purposedescribed.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
